Overview
The BEVRLink relay module is a user-friendly solution suitable for users of all levels of experience. With clear documentation and easy setup, this module is perfect for beginners. It features 4 relay channels and 4 voltage-free input channels, each equipped with a button for convenient testing. The inputs can be connected without external power, and the module can send interrupts to a manager (e.g., Raspberry Pi) on input change. The onboard LEDs indicate relay status for easy monitoring. The BEVRLink relay module offers a standard rail mount bottom case, selectable I2C address, and an optional I2C 4.7K pull-up, making it simple to set up and use. Whether you're a beginner or an experienced user, the BEVRLink relay module is an ideal choice for controlling relays and inputs in your system.
Just connect the button to the input and ground, no extra power is required. Or connect the transistor outputs from sensors and digital switches. A 5V 5mA is flowing out the input connector to sense if there is a short to ground or not, this is called wetting current in the industry.
A button on each input allows for quick and easy test or usage of the inputs in your system.
The 4-Channel Relay Board is a versatile and compact solution for controlling high-power devices from a low-power microcontroller or switch. With 4 high-quality relays, this board can switch up to 5A 250V AC or 5A 30V DC loads, making it suitable for a wide range of applications. The board is powered by a 12V/2A DC Jack power input and features a 12V output connector for powering additional boards or loads.
